I have used Yaz for a month now and have not noticed anything yet as far as less hair growth ( I'm also on my second month of Spiro so I hope at least the spiro kicks in soon to help). I'm sure it is too soon, Though. I don't believe there is any difference between YAZ and Yasmin other than the fact that YAZ is giving you more hormones cuz it is a 24 day active pill vs. the standard 21 day pill that Yasmin is. Your period may just be a bit shorter. The progestin used in both is a new one called drospirenone. Interestingly, both Yasmin and YAZ say on their websites that they are the ONLY pill that offers this drospirenone , which has very low androgenic properties, but maybe thats cuz they came out simultaneously or something and didn't know about the other..just seems odd and unlikely.
I have been breaking out really badly all over my face and on my back and it won't go away. It did start a month before I started the pill and a week after starting to apply Vaniqa. The confusing thing is that I stopped the vaniqa 3 weeks ago and the acne has not gone away.Either the Vaniqa takes a very long time to get out of your system or the YAZ has contributed.
